This adds support for specifying multiple directories in the
GSETTINGS_SCHEMA_DIR environment variable by separating the values
using G_SEARCHPATH_SEPARATOR_S (colon on UNIX-like systems).
While programs could already register multiple custom GSettings schema
directories, it was not possible to achieve the same without writing
custom code, e.g. when using the gsettings command line tool.
Fixes#1998.
By default (on POSIX) we would be inheriting thread priorities from the
thread that pushed a new task on non-exclusive thread pools and causes a
new thread to be created. This can cause any non-exclusive thread pool
to accidentally contain threads of different priorities, or e.g. threads
with real-time priority.
To prevent this, custom handling for setting the scheduler settings for
Linux and Windows is added and as a fallback for other platforms a new
thread is added that is responsible for spawning threads for
non-exclusive thread pools.

Currently the code generated by gdbus-codegen uses
G_DBUS_CALL_FLAGS_NONE in its D-Bus calls, which occur for each method
defined by the input XML, and for proxy_set_property functions. This
means that if the daemon which implements the methods checks for
G_DBUS_FLAGS_ALLOW_INTERACTIVE_AUTHORIZATION and only does interactive
authorization if that flag is present, users of the generated code have
no way to cause the daemon to use interactive authorization (e.g. polkit
dialogs).
If we simply changed the generated code to always use
G_DBUS_FLAGS_ALLOW_INTERACTIVE_AUTHORIZATION, its users would have no
way to disallow interactive authorization (except for manually calling
the D-Bus method themselves).
So instead, this commit adds a GDBusCallFlags argument to method call
functions. Since this is an API break which will require changes in
projects using gdbus-codegen code, the change is conditional on the
command line argument --glib-min-version having the value 2.64 or
higher.
The impetus for this change is that I'm changing accountsservice to
properly respect G_DBUS_FLAGS_ALLOW_INTERACTIVE_AUTHORIZATION, and
libaccountsservice uses generated code for D-Bus method calls. So
these changes will allow libaccountsservice to continue allowing
interactive authorization, and avoid breaking any users of it which
expect that. See
https://gitlab.freedesktop.org/accountsservice/accountsservice/merge_requests/46
It might make sense to also let GDBusCallFlags be specified for property
set operations, but that is not needed in the case of accountsservice,
and would require significant work and breaking API in multiple places.
Similarly, the generated code currently hard codes -1 as the timeout
value when calling g_dbus_proxy_call*(). Add a timeout_msec argument so
the user of the generated code can specify the timeout as well.
Also, test this new API. In gio/tests/codegen.py we test that the new
arguments are generated if and only of --glib-min-version is used with a
value greater than or equal to 2.64, and in gio/tests/meson.build we
test that the generated code with the new API can be linked against.
The test_unix_fd_list() test also needed modification to continue
working now that we're using gdbus-test-codegen.c with code generated
with --glib-min-version=2.64 in one test.
Finally, update the docs for gdbus-codegen to explain the effect of
using --glib-min-version 2.64, both from this commit and from
"gdbus-codegen: Emit GUnixFDLists if an arg has type `h` w/
min-version".
Notification id (notify_id) is generated by notification daemon and
is valid only while daemon is running. If notification backend will
resend/reuse existing notification id (replace_id) after notification
daemon has been restarted it could replace wrong notification as same
id now can be used by different notification.
The timezone(3) man page on Fedora 31 describes the start/end
field in the POSIX TZ format as follows:
[quote]
The start field specifies when daylight saving time goes
into effect and the end field specifies when the change is
made back to standard time. These fields may have the fol‐
lowing formats:
Jn This specifies the Julian day with n between 1 and
365. Leap days are not counted. In this format,
February 29 can't be represented; February 28 is day
59, and March 1 is always day 60.
n This specifies the zero-based Julian day with n
between 0 and 365. February 29 is counted in leap
years.
Mm.w.d This specifies day d (0 <= d <= 6) of week w (1 <= w
<= 5) of month m (1 <= m <= 12). Week 1 is the
first week in which day d occurs and week 5 is the
last week in which day d occurs. Day 0 is a Sunday.
[/quote]
The GTimeZone code does not correctly parse the 'n' syntax,
treating it as having the range 1-365, the same as the 'Jn'
syntax. This is semantically broken as it makes it impossible
to represent the 366th day, which is the purpose of the 'n'
syntax.
There is a code comment saying this was done because the Linux
semantics are different from zOS and BSD. This is not correct,
as GLibC does indeed use the same 0-365 range as other operating
systems. It is believed that the original author was mislead by
a bug in old versions of the Linux libc timezone(3) man pages
which was fixed in

for the ignore_leap parameter. Fortunately the method impl
also had an inverted test cancelling out the first bug.

The implementation has always wrapped at 76 characters, rather than 72,
ever since it was introduced in commit 5cf8f1d4a8 in 2006. At this
stage, it’s probably best to fix the documentation rather than the
implementation.
The likely bug in the implementation is the comparison
```
(++already) >= 19
```
19 × 4 = 76, so it seems like an off-by-one error in the comparison.
What was actually wanted was 18 × 4 = 72.
Thanks to Simon McVittie for the investigation and diagnosis.

This should fix our CI, which is currently failing on any system which
requires using the zlib subproject (typically VS systems) as wrapdb is
down. Work around that by pointing our wrap file at the underlying
github hosting instead.
See https://github.com/mesonbuild/meson/issues/6446#issuecomment-574241715
This can be reverted when wrapdb is working again.

Previously, the documentation indicated that it was possible to call
g_tls_connection_handshake() after an initial handshake to trigger a
rehandshake, but only if TLS 1.2 or older is in use. However, there is
no documented way to ensure TLS 1.2 gets used. Nowadays, TLS 1.3 is used
by default.
I'm removing support for rehandshaking from glib-networking, as part of
a large refactoring where keeping rehandshakes would have entailed
significant additional complexity. So let's update the documentation to
indicate this is no longer ever supported. Applications should not
notice any difference.
Also, sync some previous handshake and rehandshake changes from
GTlsConnection to GDtlsConnection that were missed by mistake. I
try to remember to always update GDtlsConnection when touching
GTlsConnection documentation, but it's easy to forget.
We used XML to markup when we should have used our own brand of markdown
instead. This fixes the example being unreadable unless we trimmed the
XML away from it.
We had one before, but the runner machine was too flaky to be useful.
Re-add it now that the Foundation have sorted out a more reliable
machine. (Thanks!)

For the check "if (error != NULL)" to work as expected, the
create_server() (and create_server_full()) functions need to make
sure to return an error for all the possible failures, but this
might not always be the case.
Catch all the failures by testing for a non-NULL return value if there
was no error.
Similar to 3837b83f, glibc memcpy is declared with the first two
arguments annotated as non-null via an attribute, which results in the
undefined behaviour sanitizer considering it to be UB to pass a null
pointer there (even if we are copying no bytes, and hence not actually
dereferencing the pointer).

This shouldn't make any difference, because this code should only ever
be running in the main context that was thread-default at the time the
task was created, so it should already match the task's context. But
let's make sure, just in case.
They didn’t match the prototype generated by `gdbus-codegen`, which
meant that the FD list was being iterated incorrectly. Secondly, the
document ID list returned by the method was not NULL terminated, which
could lead to reading off the end of the list.
Somehow, neither of these bugs caused problems on Linux, but they did
cause problems on FreeBSD.

Sadly, I forgot to update the documentation of
g_dtls_connection_handshake() last time I touched
g_tls_connection_handshake().
Let's also drop mention of STARTTLS, since that would use normal TLS,
not DTLS.
By removing the cached global proxy in gdocumentportal.c, we can
re-enable the checks for proper shutdown of the session bus connection
in the dbus-appinfo.c test.
We can't use session_bus_down() in the test since gdocumentportal.c
holds a reference to the session bus connection, preventing it from
being finalised.
